You do not have an owner's manual? If not, then you really need to get one. In the mean time, Park the vehicle on a level surface. Drain the oil and change the filter. Pour in 4 qts. of oil and start the engine. Let run for 45 seconds and shut down. Let it set for 45 minutes and check the oil level and add as necessary to reach the full mark. You now know the capacity.
